I understand what you're saying. I don't know why some posts get lots of big votes and some really good posts struggle to get to 50 cents.
It took me almost 5 months of posting almost every day, and a couple of lucky whale votes to get to where I am now, and my full vote is still only worth 8 cents. I keep doing posts because every little bit of votes that I get adds a little bit to my steem power. Some people buy lots of steem to start with to give them more steem power, but I can't do that, so I just keep writing posts.
